We are using the new chroma key in composure 5.7 and in general it is much better than the old one, however it seems to have far less controls to fix issues. I do not see any way to fix the edge of the key or erode the alpha channel to remove edge problems. I see you have a FXAA layer pass you can add, but when I enable that I don’t see anything change on my screen, not a single pixel seems to change when I enable or disable that. Is that function working? or is there something else I need to do to enable it?
Here is a snip of our key from a Hitachi Z-HD6000 camera and we have a line around the edge sometimes like you see here in this pic. The really strange thing is that it seems to move around if you move your hand back and forth it is like this black edge around it seems to “lag” behind the video as you move, as if it is a separate key/fill and the alpha is lagging behind.
